The LA4742 is a 45 W 4-channel power amplifier IC for car stereo systems. It features a built-in bridge circuit and the ability to radically reduce the number of external components required.
| Parameter | Symbol | Conditions | Ratings | Unit |
| Maximum supply voltage | VCC max1 | Signal present | 18 | V |
| VCC max2 | No signal (for 1 minute) | 26 | V | |
| Maximum output current | IOpeak | 4.5/ch | A | |
| Allowable power dissipation | Pd max | With an arbitrarily large heat sink | 50 | W |
| Operating temperature | Topr | 40 to +85 | °C | |
| Storage temperature | Tstg | 40 to +150 | °C | |
| Package thermal resistance | jc | 1 | °C/W |
• Maximum output power: 45 W * 4 channels (VCC = 14.4 V, 4 load, 1 kHz)
• 40 W * 4 channels (VCC = 13.7 V, 4 load, 1 kHz)
• Requires only seven external components and does not require an oscillation prevention RC circuit, a noise filter, or a BS capacitor.
